Our cyber world fell apart yesterday morning when US Weekly dropped a terrible "truth" bomb: Emily Maynardhad cheated on Jef Holmin a series of sexts, and he discovered the evidence while on a family vacation in Myrtle Beach, South Carolina.Emily and Jef were quick to dismiss the rumors, but it looks like Us Weekly's source has come forward...and it's none other than Jef's brother, Mike Holm!"I can tell you that it's all 100% true," Mike tells Us. "I was there and I heard the fight and watched the whole thing go down, Emily leaving and everything. I love my brother very much and, like the rest of our family, I just want him to be happy."We have no idea why Mike would talk to the gossip mags when Emily and Jef went on the record saying the story was false, but the whole thing seems mighty fishy. Either way, Mike says he's rooting for Jef and Em just like the rest of us. "We all love Emily, too. Mistakes happen, we all get that," he says. "I hope they can work it all out, but as far as your story goes, it's all true."Now, before you spiral into a pit of ennui — remember that Mike's story might not be accurate. After all, why would Jef's own brother sell him out? "It's crazy what people will do, even family members, to see their name in a magazine," Jef tweeted on August 23rd.Who knows why Mike has spoken out, but Jef and Emily are officially together and insist they are happier than ever — despite these nasty rumors.
